Offset printing innovation is not only reflected in the green environment of the machine. CTP is widely used in rotary offset printing presses, the commercialization of color offset presses, the development and application of offset printing UV inks and waterless inks, once again aroused the desire of the domestic printing and packaging industry to invest in offset presses. Li Renchao, North China Sales Manager of Shanghai Peony Ink Co., Ltd., said, “In the future, the printing and packaging industry is optimistic about flexo printing, but offset and offset printing inks will retain about 40% of the application rate for a long time. For example, domestic beer is marked for some time. Prevailing intaglio, but due to fierce competition in the industry, there are frequent changes, and now it is still dominated by offset printing."
Shanghai Peony Ink Co., Ltd. (originally Shanghai Ink Factory) is the largest lithographic offset ink producer in China with an annual output of 15,000 tons, which firmly captures 80% of the market share in the south and expects to expand the northern market in 2006. Peony ink is one of the few large-scale ink manufacturers that have no foreign investment in China. With the help of cooperation with Sikhbae before 2000, management technology and quality service can be compared with Hanghua and Toyo, and the number of employees is reduced from 1,400 while the output is increasing. 600 people.
1995-2005 is the tenth year for the vigorous development of domestic offset printing inks, with the total volume increasing from 30,000 tons to 120,000 tons. The offset range is complete, including high-grade offset bright fast-drying inks, cardboard inks, matte powder inks, press rotation inks, Coldset rotary ink, UV curable ink, synthetic paper ink, iron printing ink and new thermosetting rotary ink. Manufacturers are located in Shanghai, Tianjin, Hangzhou, Shenzhen and Taiyuan, mostly in joint ventures. During the "Eleventh Five-Year Plan" period, China's printing and packaging are expected to maintain a growth of 10%, and the growth rate of offset printing inks should be 9%. In the future, products should develop toward multi-color, high-speed, quick-drying, environment-friendly and pollution-free and low-consumption.
Environmental offset printing ink
For a long time, the air index of the offset printing workshop is difficult for the printer to feel comfortable. Although the stupid ink is no longer allowed to be used, the odor emitted by the solvent-based highly volatile ink still threatens human health.
Yan Jing Beer, President of Beijing Shuangyan Color Printing Co., Ltd., said: “Many printing houses used offset printing to print wine labels, followed technical changes and turned to flexo printing, including breweries' subordinate printing and social independent printing plants. Flexo Ink The environmental friendliness of the process is in line with the actual needs of future consumption."
In order to meet the market demand, offset press manufacturers and ink manufacturers are all committed to the green printing of traditional offset printing. Entering Huali Packaging's closed offset printing workshop, the air duct exhausts all the volatile gases. The site is clean and tidy, and the air is fresh. Zhang Xiaojun, the general manager, highly praised Kobayashi's ability to process ink in an environmentally friendly manner.
Environmental protection and non-pollution have become the primary indicators for today's printing companies to purchase ink. Ink products require ISO 14000 environmental system certification. End-users also request VOCs and residual solvents for printing and packaging products. It can be seen that environmental awareness is promoting new types of low toxicity and harmlessness. The development of environmental protection ink.
The non-environmentality of offset printing inks is mainly reflected in the odor, and newspaper ink is the most contaminated. The reported printing workshops generally have relatively high humidity, and Mexico Oil uses mineral oil as a solvent, resulting in a strong irritating odor of ink and solvent, which directly affects the health of operators.
The common problem is that if the ventilation is increased, it will cause flying ink, and weakening the air volume will enlarge the odor of the ink. Currently, due to the compositional restrictions, the environmental protection ink produced has poor permeability and affects the drying speed and does not meet the requirements for high-speed printing. Newspaper offset inks must ensure the printing effect, but also have environmental performance. The printing industry has a high demand for environmentally friendly inks.
Micro-tile color offset printing
The display of products through storage and transportation packaging, the promotion of product design concepts and market demand have promoted the rise of direct offset printing (after offset printing) of corrugated board technology. Offset four-color printing has traditionally been regarded as the most ideal printing configuration. Corrugated board has undergone continuous refinement and transformation. Types G and N have marked the completion of direct offset printing. The existing Roland 700, 900 and KBA-Planeta offset presses can directly print miniature corrugated cardboard with slight adjustments. There is no washboard phenomenon, and no corrugation variant reduces the strength of the board. Fine corrugated packaging using offset printing, printing effect is good, colorful, with strong color performance capabilities, after coating UV Varnish not only achieved the effect of waterproof, but also make the compressive strength of the package has increased. After the successful application of offset printing technology, the corrugated box replaces the cardboard box.
Since the advent of mini-corrugated media in the 1990s, the market utilization rate has continued to rise. The U.S. is growing at a rate of 2% every year. The share of Europe in 2004 is estimated at 12%, and it is mainly due to the small corrugated type of F-type, G-type, and N-type. At present, 30% of the products in folding carton packs can be changed to miniature corrugated boxes.
China's micro-corrugated board has just started, limited to the production of E-type corrugated, in terms of quality and grade of paper products, fewer varieties, low grade, need to be vigorously developed. Many domestic printing and packaging companies have imported four-color offset presses, which provide the necessary equipment basis for micro-printing. The total corrugated packaging volume in China is 15 billion square meters. If 10% is transferred to microwatts, 3 grams per square meter of offset ink will add 4,500 tons of offset ink demand.
Fast commercial color printing
Due to the rapid development of offset press technology, medium- and small-format multi-color offset presses are entering the domestic commercial color printing market on a large scale. This is a result of commercial packaging products moving towards differentiation, functionalization, and short-form printing. The technology for high-speed medium-format multi-color offset printing, such as on-line coating, UV printing, and reverse printing, is deployed on medium and small-format offset presses, making it flexible, fast, and technologically advanced, increasing the added value of printed products, and expanding the application fields.
The two major changes in the printing market are the multiplicity of prints, high quality, small prints, and short-term cycles that have become the general trend of the entire market; second, the three major players in packaging and trademark printing, publishing and printing, and social business printing have invested in the introduction of equipment. , Accelerate technological transformation, optimize productivity, and take the road to innovation and technological innovation. Some leading printers have begun to use four-color offset printing and online light (or UV offset printing process), indicating that the short-run color printing industry has become a major area. Heidelberg launched the Speedmaster SM52 on-line coating and UV offset press for this purpose. Catering to the new market trends, this undoubtedly brings business opportunities to many small offset printing ink companies.
